Hello,
* *Maybe you forgot to power on?*
ok I tought Linux ELDK was a community not a way to laugh about people ?
* *Sorry, but you did not give any details, like which exact
software versions (U-Boot and Linux, whiche xact git commit ID)
you are using,*
I already put some information but here they are again :
- U-Boot 1.3.4
- Linux 2.6.29 rc7 fec6c6fec3e20637bee5d276fb61dd8b49a3f9cc
**
**
* **which exact commands you are running to configure and build the
****software**
To configure the kernel :
make ARCH=powerpc xconfig
To compile :
PATH=$PATH:/opt/eldk/usr/bin:/opt/eldk/bin
export CROSS_COMPILE=ppc_8xx-
make ARCH=powerpc uImage
Config file .config
see below pls
*
****how you build the device tree blob****
Compile FDT (see below pls) with DTC v1.2.0:
./dtc -b 0 -V17 -p 0x1000 -I dts -O dtb ./mpc885ads.dts >
/tftpboot/mpc885.dtb
* ********how exactly you load and boot the image********
I load it with tftpboot :
tftpboot 300000 uImage
tftpboot 500000 mpc885.dtb
Then I boot without ramdisk for the moment :
bootm 300000 - 500000
********
********
* ********what your exact boot argument settings are********
******** ******** bootargs=root=/dev/rd/0 console=ttyCPM0 init=/linuxrc rw mem=40M
********
=> printenv
********bootcmd=bootm fe080000 fe160000
bootdelay=5
baudrate=38400
ethaddr=40:00:00:00:00:01
ethact=FEC ETHERNET
ipaddr=172.28.20.221
serverip=172.28.20.220
bootargs=root=/dev/rd/0 console=ttyCPM0 init=/linuxrc rw mem=40M
stdin=serial
stdout=serial
stderr=serial********
********
* ********which root file system you are using, etc. etc. ********
I tried to boot with a ramdisk and busybox but the result is the same.********
********
* ********So how do you expoect us to be able to guess what might be
wrong on your system?********
I hope there are more usefull information.
Best regards,
Sylvain ANDRE.
